Moreover, we cannot guarantee that the code in the run-time engine follows the assumptions built into the optimizer so even if we try to fine-tune memory to get the right cost, we can t guarantee that the run-time engine will behave for us anyway Untangling the oddities and conflicting bits of information, we can finally work out that the value of 617 can be derived as follows:.

CommandText = _ "IF EXISTS(SELECT PlaceID FROM Place WHERE PlaceID = @PlaceID)" & _ " SELECT COUNT(*) AS Attendees, @PlaceID " & _ " FROM (SELECT UserID" & _ " FROM TimeLapse" & _ " WHERE PlaceID = @PlaceID" & _ " GROUP BY UserID) Users" & _ "ELSE" & _ " SELECT -1" MecmAttendeesCountConnection = MecnFriends ..etc..

You can t set the property to this value through the Properties browser or the Query Builder because the designer does not support IF statements (and many other valid SQL statements). Therefore, it will fail to set it. Once you set it this way, however, it will be properly reflected in both and preserved when you make changes to other properties. 2. Import the following namespace at the top of the code-behind class: Imports System.Web.Services.Protocols 3. Go to the GetAttendees() method and modify the code as follows: <WebMethod()> Public Function GetAttendees(ByVal placeId As String) As Integer cnFriends.Open() Try ' Set the place to filter by cmAttendeesCount.Parameters("@PlaceID").Value = placeId Dim count As Integer = CType(cmAttendeesCount.ExecuteScalar(), Integer) If count = -1 Then Throw New SoapException("Invalid Place identifier!", _ SoapException.ClientFaultCode, Context.Request.Url.AbsoluteUri) End If Return count Finally cnFriends.Close() End Try End Function Now, whenever the user passes in a place ID that doesn t exist, the application will throw a SoapException, which inherits from the standard Exception class. 4. Now that you ve altered this method so that it specifically throws exceptions, you must update your consumer application to ensure that it doesn t fall over when the exception is thrown. In other words, you need to make use of this exception, by catching it whenever it is thrown. To do this, drop a new Label control at the bottom of the Default.aspx page in the Acudei project and set the following properties for it: ID: lblError Visible: False EnableViewState: False ForeColor: Red 5. Locate the Page_Load() event handler in the code-behind code. Add the following try catch block: Private Sub Page_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim friends = New Acudei.FriendsService.Partners
